Entacapone is a medicine used to manage movement symptoms. Working alongside other therapies, Entacapone ensures that active components stay in the nervous system longer.
Entacapone belongs to a group of drugs called COMT inhibitors, which help keep the effects of other Parkinson's medicines longer in the body. It is the active ingredient in combination products such as Stalevo, where it works alongside levodopa and carbidopa.
Entacapone is added to reduce "off" periods and smooth out the highs and lows of movement control for people with Parkinson's disease who notice their regular pills fading too quickly. Most adults with Parkinson's disease who take levodopa and notice fluctuations find it helpful. It is also used in people who need a steadier response to levodopa throughout the day.
After you swallow a tablet, entacapone travels to your bloodstream and blocks an enzyme called catechol-O-methyltransferase (COMT). COMT normally breaks down levodopa; by blocking it, entacapone lets levodopa stay active longer, giving you smoother symptom control.
Women who are pregnant, planning a pregnancy, or breastfeeding should use extra caution because safety data are limited. People with severe liver or kidney problems should discuss the risk-benefit balance with a health professional. Alcohol can increase certain side effects, and entacapone may interact with other dopamine-acting medicines or some antidepressants, so check the labeling of any other drugs you take. For exact interaction details, refer to the medication's patient information leaflet.
Older adults and people with existing liver disease may notice side effects more often. Those taking multiple dopamine-boosting medicines can also be more sensitive. A history of allergic reactions to similar drugs may increase your risk.
Store tablets at room temperature, away from excess heat, moisture, and direct sunlight. Most Stalevo tablets are taken for the long term, but the exact treatment length can vary between products. For detailed usage, dosing, and administration, refer to the specific medication's clinical information.
